If-Then Statement with DataBinding in Android

Here is small code snippet for If-then statement in XML file.

As we know we don't need to create object of our control/view when using DataBinding, but what if we want to hide some views based on a condition.

For example, i want to hide TextView of email when there is no data for email. Here is small code snippet for that.

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>

        <variable
            name="user"
            type="<package name>.UserModel" />

        <import type="android.view.View"/>
    </data>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="@{user.email}"
             android:visibility="@{user.email.trim().length()>0 ? View.VISIBLE : View.GONE}"/>

    </RelativeLayout>
</layout>
